STAGE CIRCUIT AND SCAN DRIVER USING THE SAME

摘要

There is provided a stage circuit capable of minimizing a mounting area. The stage circuit includes: an output unit configured to supply a voltage of a first node, an i-th (i is a natural number) carry signal, and to supply an i-th scan signal in response to the voltage of the first node, a voltage of a second node, and a first clock signal, a controller configured to control the voltage of the second node in response to the first clock signal; a pull-up unit configured to control the voltage of the first node in response to a carry signal of a previous stage and a voltage of a first node of the previous stage, and a pull-down unit configured to control the voltage of the first node in response to the voltage of the second node and a carry signal of a next stage.
